yes yes i agree completely thats the snswet answer* 25 a b c d 46:77 77/55
Divide it into chunks of area you can find. One way to divide it is
.. a rectangle 2 mi x 5 mi at upper left.
.. a rectangle 8 mi x 6 mi down the middle
.. a rectangle 3 mi x 4 mi at lower right
.. a triangle 5 mi x 6 mi at lower left
Then the sum of areas is
.. (2 mi)*(5 mi) +(8 mi)*(6 mi) +(3 mi)*(4 mi) + (1/2)*(5 mi)*(6 mi)
.. = 10 mi^2 +48 mi^2 +12 mi^2 +15 mi^2
.. = 85 mi^2
Equation in point slope form is written as:
y = mx + c, where m is the slope of the line and c is the y-intercept
To determine the equation when slope is given and (x,y) coordinates are given, use the below formula:
(y - y₁) = m × (x - x₁) .................. (i)
We have been given that m = 3, x₁ = 2 and y₁ = 1)
Substituting the values of m, x₁ and y₁ in (i)
(y - 1) = 3 × (x-2)
⇒ y - 1 = 3x - 6
⇒ y = 3x - 5
So the required equation is y = 3x -5, here 3 is the slope and -5 is the y-intercept
3/4J - 1 = 16 <== ur equation
